To all whom t may concern.'

` Be it knownv that I, EDWARD J. Donna- STEI'N, a citizen of the United States, resid.- ing at. Blue Island, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Gathering Reels7 `of which the following is a specification.

This invention vrelates to improvements in gathering reels of the type adapted to be mounted on ,mining locomotives, and has for its principal object to provide an improved device of the class mentioned.

More specifically. this invention relates to i i cluding a friction segmentmovable radially into engagement with the reel drum in orderl to drive the latter positively in one direction and to afford a brake means whenv the reel is rotated in the opposite direction.

The object of the present invention is to provide a counterweight so that the radially movable segment may be effectively operated at high speeds. After experimentation, it has been found necessary to provide this counterweight to overcome the centrifugal force engendered-by high speeds.

The invention may best be understood by reference to the accompanying drawingsl which illustrate one form in which it may be embodied.

In these drawings: Figure1 is a side view of a reel with the driving mechanism shown in-vertical crosssection.

Figure 2is an end view of the reel with the driving sprocket and cover plate removed, showing the driving mechanism in driving `position in full lines and in braking position in dotted lines.

Referring now to the details ot' construction illustrated in the drawings:

" The gathering reel A is mounted on shaft B having a suitable drivinglsprocket C at one end thereof.l The reel and associated parts are Vsupported on a suitable frame D.`

in the periphery of the disk 10, as shown. A

frame member 12 is also journaled on the shaft B and is provided with two pairs of* laterally extending arms 13 and13, 13% and 13a. A `guide rod14 is slidably mounted through the arms 13 and 13 on one side of the frame 12, and a parallelly disposed guide rod'14'f1 is similarly mounted on the oppositeV side of the frame through the arms13a` and 13a. An `arcuate brake shoe 15 is provided with a friction piece 16 of fibrous material,

or lthe like, and is adapted to engage the brake drum 17 forming a part of the' reel to drive the latter. An arcuate counterweight,` similar in form to the brake shoe 15, is also provided. The guide rods 14 and 14a' extend into suitable lugs 18,- 18 at one end,

formed adjacent'the opposite'ends ofthe" brake shoe 15,` and into flugs 18a, 18%for1ned adjacent the opposite ends of thecounter weight, on, the other end, which construction permits radial movement of said brake shoe and counterweight, together with their supporting framev 12. `'The counterweight is not intended to engage the inner bearing surface ofthe drum 17. A lever 1,9 is pivlotally mounted at20 to one of the arms 13a. The outer end 22 of said lever arm 'engages a movable .pin 23 projectingl upwardly through the lug 24 integral with the frame 12. The upperv end 26 of the pin 23 extends intoV a suitable annular stud 27 forming a part of the shoe 15.

the outer face of the brakeshoe 15, as shown. A nut 30 has threaded engagement on the pin 23. Variation in the tension of the tion of the nut 30 on said pin. The spring 28 is normally adapted to hold the pin 23 in engagement with the outer end-of lever arm 19. The inward or downwardmovement of A spring 28 is inter- "posed between the annular portion-25 and spring 28 is afforded by adjusting the posi-"- said arm is limited bya stop 31 on the frame-'i5 12. A set screw'38 is mounted on a projection 39 integral with the frame 12 and is adjustable to limit the outward or vupward movement of said'lever arm. A pawl 5l-is pivoted at `36 on thearm'lQ and is' provided"` `with a. compression spring 37 adapted to hold is advancing toward the point of oonnooti'on oftheconductoi' cable to the supply wires.

Yas tno diekl'vis une 1-otatodg1t11o pawi 3s ougages'I lone offnotches 11,l as' slfrown" in Figure?, whereupon thel lever arm 191s piavotod" outwardly, thereby moving. Vthe pin 23 i'nna radial direction'. vvThe spring is thereupont compressed and the bralre shoe 1s yforced 'into driving engagement with A the 4drum 17 thereby transmitting the driving torque tol ,the r'ee'l.-` As already suggested, it

isdsi'rabl'e'to maintain a tension on the condfl'ictorL cable' -as is being* wound' on4 the reel and, to this' end the set screw 38 limits th.' amount o'f relativo: movement of the frioftic'inV shoe 15 aindv frame 12. By means of tlii arrangement? the' disk' may be rotzt'edatiislightl-y greater speed than is' nec- 'sry to retrieve" the conductor' c'ableqon the reel, andthemovement of the friction shoe uryl-fp'islimited so toj limit the' amount'of fictional oota'otad thus provide a slippiiigl frictional driving engagement with the drum'. Itwillbe noted that the 'arrangemoet or 'the dog 46 and notches 11, 11, is

f siichlthat the reel can" be'diiven in' bult one direction to wind the cable thereon;

lIlt'efer'ring' now to ythe arrangement for applying b'ral'e to the reel during the time that locomotive is movin`g` away from point o'f,A- connection' ofv the conductor 'cble and the' latter is being withdrawn thfreel,` it will be seen thatv the spring l28 serves toV maintain tliebrake shoel 15 in oonstant contactnwitliA theV drum 17 so that whe'nthe' cable is unwound from the reel,

and tli'e'latter isrotat'ed in a counter-clock- Wise diotiomthe entire frame member 12 andthe shoe 15' carried thereby will be roy"ta'tedl into al position sliow'n in dotted lines v inFi'gu-re 2, in which thev stop 45 engages thedogif,v` 46A'1i1ounted o'n the frame D. In

ltIiis position thelfbralie 'shoeis under sutil- "cie'ntf tenslonof ythe spring 28-to retard the lrotation yof the cable s'o as to eliminate the da'ger `of. over-running the conductor cble.

.i lthbugh I have ,shown and' described one form in which -my invention may be embodied",` it will be understood that the arrangement and construction of the various parts may be altered without departing from the spirit and scope of my invention.
